MECHANISM FOR TRANSMITTING MOTIONJ T 0 all whom it may concern: V

Be it known that I, GILBERT P. MARINIER,

' a citizen of the United States, residing at Pontiac, in the county of Oakland and State'of Mlchlgan, have nvented new and useful Improvements in Mechanism for Transmitting Motion, o-fwhich the following is a specification. 5 a a I My present invention pertains to'mecha n'ism for transmitting motion, and more particularly to mechanism designed forembodiment in farm implements intended for 7 use in conjunction witlrtractors, and is designed more particularly as an improvement upon the farm implement constituting the subject of my Letters Patent No. 1,206,568, dated November 28, 1917;

a The generalobject of my present invention is the provision of a peculiar and highly advantageous mechanism for transmitting motion.

Another object is the provision of such mechanism designed more particularly for use to advantage in combination with a trac tor, including means for moving a plow or cultivator to and from working position;

said'means being. so constructed and arranged that it is adaptedto strongly maintain a plow or cultivator in working position, and also-1n ldle ralsed position.

lV1th the foregoing 1n mmdthe invention will be fully understood from the following description and claims when the. same are read in connection with the draw- 35 ings accompanying and forming part of this specification, in which:

Figure 1 is a general View in side elevation illustrating my improvement with the plow in raised or idle position.

4:, d are plow or cultivator beams, to which is pivoted at 5 the shank 6 of the plow 7:

the said shank having a forwardly reaching arm 8, notched at its forward end as indicated by 9. Connected to and extending forwardly from the pintle 5 is a link bar 10 to which is pivoted at 11 a retaining latch 12, having a protuberance 13 that is normally disposed in the notch 9 of the shank arm 8. The latch 12 extends laterally with respect to the link bar 10, and con nected to said latch is one end of a retractible spring 14: the opposite end of which is adjustably connected with a lug l5 onTthe link bar through the medium of 'a threaded bolt 16 that bears in said lug.

Manifestly by adjusting the bolt 16 the tension of the spring 14 may be readily regulated as conditions require; and it will also be understood that the spring 14: is sufficiently strong to hold the plow to its work under normal conditions, and yet in the event of the plow encounteringa large stone or the like, the spring will give and permit disengagement of the plow shank from the latch 12 so as to permit the plow to clear the obstruction without being in jured by the collision.

' The link bar 10 is pivotally connected at 17 to a crossbar 17* between pendent arms 18 of bell cranks that are fixed on a shaft 19 and have their other arms 20 connected through links 21 with arms 22 of bell cranks that are fast on a transverse ing member 28 having a notch 29 and concave edges 80, the latter being adapted to be opposed to, the perimeter of a gear 30 .which is fast on the shaft 19 and is equipped with stop pins 31 and 32. The said gear 30 is also equipped with atappet33.

Interineshed with the gear 30 is a worm 34 on a shaft 35 which shaft is journaled in the frame 3, and is equipped with a loose gear 36. Mounted in the frame 3 and disposed above the shaft 35 is a bar 37 having an upstanding arm 38 to coiipcrate with the stop pins and also having a portion 39 for the engagement of a gear shifting lever 40. The said lever 40 extends below the bar 37 and is engaged with a clutch member 4142 which is mounted to rotate with and move endwise on the shaft 35. Fixed at 45 on a shaft 50 is a drive pulley, and also fixed on the shaft 50 is a pivoted gear 44. The gears 36 and 44 are provided at their inner sides with clutch faces complementary to the clutch member 4142. At 46 is a gear interposed between the gears 36 and 44 and designed when the clutch member 4142 is in engagement with the clutch face of the gear 36 to transmit motion from the gear 44 to the gear 36, whereupon motion will be transmitted from the gear 36 to the shaft 35 through the medium of the clutch member 41-42. lVhen the clutch member 41-42 is engaged with the gear 44, the shaft 35 will be rotated from the shaft 50 through the medium of the gear 44 and the clutch member 41-42. hen the clutch member 41-42 is out of engagement with both gears 36 and 44, the shaft 35 will be left idle.

It will be gathered from the foregoing that through the medium of the gear shifter lever 40, the clutch member 41 42 may be moved endwise on the shaft 35 so as to engage either the gear 36 or the gear 44 as conditions require. It will also be gathered that when the gear 30 is rotated its tappet 33 will coiiperate with the cam 28. Manifestly when the clutch member 41-42 is in neutral position as shown in Fig. 1, the worm 34 by cooperation with the gear 30 will strongly secure the plow beam in the position in which the same is placed.

Having described my invention what I claim and desire to secure by Letters-Patent 1s:
